Add AddQueryResource alternatives for bulk unpublish query params in BulkUnpublishService.cs.

Description
In BulkUnpublishService.cs, two comment-only lines were added to document an alternative way of sending the bulk unpublish options:
skip_workflow_stage_check – A commented call AddQueryResource("skip_workflow_stage_check", "true") was added next to the existing Headers["skip_workflow_stage_check"] = "true" assignment.
approvals – A commented call AddQueryResource("approvals", "true") was added next to the existing Headers["approvals"] = "true" assignment.
